Indeed. I've found that Google provides a better forum search than this buggy, ad-soaked forum does.
Instead of using the forum search function, Google "bikeforums.net credit-card touring" or "bikeforums.net" and the keyword you're looking for.

And if you want to make it possible to look up all your posts, just include a scarcely-used, and even misspelled word like "cumquat" in every post, so you can look up all your posts by Googling "bikeforums.net cumquat".
Looking up posts by user doesn't work for squat either, you'll find. But Google is still running strong.
